Obviously I don’t make an issue of it. I do the polite thing and go to parties, buy then presents etc but honestly, I find them a bit of a bore.
Actually it’s not so much the children but the parents and grandparents that I find tiresome. The constant “Oh isn’t Esme so clever. One day she’s going to be prime minister and show us all how it’s done” this said in absolute seriousness. And “Freddy is going to be a great artist one day (because he painted a dog that was definitely average for a 10yo). We need to nurture that.”
I just smile and nod along but recently my boyfriend had a go at me for “not being supportive enough of the children’s talents”. All because I “only” donated £20 to Freddy’s art project fund. He and the rest of the family were disappointed at my lack of support and interest because I “could clearly afford more”. 
Neither BF or I have children. Another bone of contention with his family as I am not particularly bothered about having children. I like my life and career. The women in his family see that as a threat to their choices. Both his mum and sister’s only ambition was to marry and have children. So I get the sarky “oh you career girls” comments regularly.
Is this relationship doomed?
